Title: Treatment of waste and a rotary kiln therefor
Inventor: WHITE KENNETH L
IPC: C02F11/13
Filed: 1987-10-02
Granted: 1993-01-05
Abstract: ABSTRACT       A method of treatment of waste materials to produce aggregates where pellets of solid/liquid waste/ clay mixture are dried by the counter-current flow of hot air (from an aggregate cooler (59)) in a dryer (29). The pellets are fed to the pyrolysis zone (47) of a rotary kiln (31) and are heated by hot gas from an oxidation zone (52) to drive off most of the volatile gases in the waste.         The remaining volatile gases and the fixed carbon in the waste are oxidized in the oxidation zone (52) of the kiln (31) and the silicates in the clay are are vitrified in a vitrification zone (53) of the kiln (31) to produce aggregates which are crushed and screened.         The volatile gases given off from the waste in the pyrolysis zone (47) is mixed with the exhaust gases from the dryer (29) to feed the burner (61) for the vitrification zone (53) and to supply oxygen via a pipe (62) to the oxidation zone (52).

Granted: 1993-11-02
Abstract: Abstract In the manufacture of optical devices such as, e.g., optical communications assemblies and optical gyroscopes, low-loss substrate-supported optical waveguides are desired. Such waveguides can be obtained by patterning a layer of deposited waveguide material and, in the interest of minimizing loss asmay be due to processing-induced surface roughness, waveguides as patterned preferably undergo a heat treatment which results in surface smoothing and in rounding of the waveguide cross section. Furthermore, in the interest of avoiding re-entrant corners between substrate and waveguide, a wetting layer may be applied to the waveguide prior to heat treatment.
